We are given the relation between x and y saying that y=3%2Ax%5E2-10.Then we are given a set of values for x and asked to calculate the corresponding values of y and tabulate them.
let us take the first value of x=2 as asked for to explain the calculation.We have to substitute this value of x in the given relation for y and x namely y=3%2Ax%5E2-10 to get at the value of y corresponding to value of x=2 .
We get for x=2...... y=3*2*2-10=2. continuing in the same manner
x=1.......y=3*1*1-10=-7
x=0.......y=3*0*0-10=-10
x=10......y=3*10*10-10=290
x=5.......y=3*5*5-10=65
